Following a report from Cable News Network last week that John Ashcroft would turn in his resignation as attorney general before the end of November, speculation was rampant over who would succeed him. Although Rudy Giuliani was on just about every pundit's "speculation list," betting is that the President would choose a more low-key and less ambitious figure with a background in law enforcement. Among those being mentioned are Deputy U.S. Atty. Gen. James Comey, U.S. Attorney for Chicago Patrick Fitzgerald, and former Deputy Atty. Gen. and Atlanta, Ga., lawyer Larry Thompson, who is African-American.
